Span device wire clamp for connecting electric power conductor and electric power device

Abstract

The invention discloses a span device wire clamp for connecting an electric power conductor and an electric power device. The span device wire clamp consists of a wire threading tube and a fastening screw bolt, wherein a front end of the wire threading tube is a wire threading tube body, a rear part of the wire threading tube body is provided with a connection fixing plate, the connection fixing plate is provided with an installation fixing hole connected with a wire connecting post of an external electric power device, a cross section of the wire threading tube body is shaped like an oval ring body of which an upper part is a flat top, a lower part of the oval ring body is a semicircular cavity while an upper part of the oval ring body is a trapezoid-shaped cavity, the fastening screw bolt is vertically arranged and is rotatably mounted in a trimming flange screw nut on a top of the trapezoid-shaped cavity, a wire clamping board is arranged on the connection fixing plate, the wire clamping board in the shape of a lath is plugged from back to front in the trapezoid-shaped cavity of the wire threading tube body of the front part of the wire threading tube, a lower part of the wire clamping board is an arc surface which corresponds to an arc surface of the semicircular cavity, a rigid wire pressing strip is mounted on the wire clamping board, and a lower end of the fastening screw bolt corresponds to an upper part of the wire clamping plate. The span device wire clamp is safe and reliable to use and high in universalization level.

Description

technical field [0001] The invention relates to a cross-diameter equipment clamp for connecting power wires and power equipment, which is suitable for connecting power wires to power transformers, switches, switches, drops, lightning arresters, transformers, busbars, and wall bushings. Background technique [0002] At present, there are many shortcomings and deficiencies in the commonly used power equipment clamps. These shortcomings and deficiencies are mainly manifested in the following aspects: 1. The bolt fastening connection is a rigid connection, and its connection resistance is large, and accidents of burns and disconnection occur from time to time; 2. Although the connection effect of hydraulic connection and mechanical crimping is good, it not only requires a variety of expensive special tools, but also takes a long time to connect, which often affects many users' delay in power transmission; 3. The specifications of the equipment clamps currently used , Dozens of v...
